Adding and CTR to my Norc - replace the reciever extension tube?

[Bolivar]

I am wanting to replace the stock on my Norc CQB with a Magpul CTR. Should I be considering replacing the existing extension tube with a milspec or will the commercial version work ok with my commercial tube. I want to have a pretty solid lock up with no wobble (and yes I am drinking the magpul kewl-aid)

Anybody with experience adding a commercial CTR to the standard Norc tube.

i put a ctr on my norinco m4 and found the tube to be very rough when machined so i bought a new commercial spec tube and everything was good to go

Was it rough has in hard to adjust or did it not lock up tight?

Found no issues using the stock commercial tube with Magpul CTR on my Norc M4.

I had the MOE on my Norc, and it was a great fit. The clamp on the CTR should take any play out of it.

Thanks for the help guys. I just go one from a fellow CGNer. Fits nice and tight. In fact it is quite hard to adjust, not that this is a concern. I don't normally adjust my stock often.

I was not expecting the difference in LOP. It is noticeably longer than the standard butt stock. Again, not a problem. Adjusted in a notch from my previous and I am good to go.
